Okay why hasn't this revolutionized the entire UK prison system and why haven't they bought yachts and luxurious hunting cabins for all their murderers and rapists if this is both drastically cheaper and more effective? Why hasn't this been adapted in the same way as fully anywhere in the world except Scandinavia? I mean officials do what they want when deciding not to execute or give elective surgery to felons or needles to druggies despite what the public thinks but this is a line they won't cross despite the supposed mountain of evidence? And its not like rehabilitation, even fairly generous rehabilitation isn't a concept thats been tried for centuries.
